Managed one Attack and one Special Ammo Boost deco out of it, everything else has been dross so far. Built a nice HBG/Spread 3 setup to pulverise it in 4mins, but it's a one-hit risky set-up.

Like you, I'd be better off farming Elders for Gleaming SS, but I can't be bothered, so I'm waiting to see what the least farmed monster will be: Lavasioth or B.Diablos, with rumors of streamstones as rewards in a flipped quest.
